VANET security and forensics: Challenges and opportunities

Abstract

Vehicular Ad hoc NETworks (VANETs) are a key part of the Intelligent Transport Systems (ITS) as they constitute an intelligent transport network where vehicles and some infrastructure collaborate to exchange messages about traffic, accidents, etc. In such context, security becomes a key component to ensure that exchanged messages were not modified or inserted for example. Consequently, a wide variety of research contributions have been recently presented to cope with this issue. This paper presents a review of most recent papers dealing with security issues in VANETs. Hence, it presents an overview of VANETs and mainly their characteristics as well as their main applications. Then, the main security challenges faced by VANETs are introduced. This is done by first listing their main security requirements, second by establishing attackers' profiles, and their attacks and third by introducing some security solutions. Finally, the opportunities and challenges related to VANETs security are presented such as Trust, Internet of Vehicle, etc.This article is categorized under: Digital and Multimedia Science > Vehicle Forensics Digital and Multimedia Science > Mobile Forensics Digital and Multimedia Science > IoT Forensics
